Wicked SICK!
I loved the whole collab, most of all the one were the engineer, medic and soldier are on the table for a dinner, when they turn out to be also spy's! xD
Great Collab my congratulations! :)
Only tip for an fix, try to make subtitles or something because some of the parts were hardly hearable.
5/5 10/10!! and I voted for an collection of half-life! :D
